RdTARYBRlCK-MACHINE.

SPECIFICATION forming part of Letters Patent No. 393,206, dated November 20, 1888.

Application filed October 1, 1887.

To all whom it may concerm lie it known that I, FnANeis C. BURRELL, a citizen of the United States, residing at La Salle, in the county of La Salle and State of lllinois, have invented certain new and useful Improvements in lh'ick-Re-pressing Machines, of which the following is a specification.

This invention relates to an improvement in brick-repressing machines; and it consists in certain peculiarities of the construction and arran gement of the same, substantially as will be hereinafter more fully set forth and claimed.

In order to enable others skilled in the art to which my invention pertains to make and use the same, l will now proceed to describe its construction and operation, referring to the accompanying drawings, in which Figure] is a vertical lohgitudinal section of the machine, taken upon the line a: a2, and showing the plungerwheel and mold wheel in elevation. Fig. 2 is a similar view through these wheels on the line y y. Fig. 3 is a top plan view. Fig. 4 is a'vertical transverse section through the line '10-'20, Fig. 2; and Fig. 5is a longitudinal section taken just inside the side frame, and showing the mold and plungerwheels in elevation the reverse of Fig. 1.

a. represents the main side frames of my machine, which are of any desired and suitable size and form, and are provided in their lower part with a pair of.belt-pulleys, a,over which runs a belt, a", to receive and carry off the finished brick, in the manner common and well known in similar presses.

In the upper part of the main frame are jonrnaled the shafts I) a, which -are upon one end provided with the gearwheels b c,whieh mesh together,andare of the same size in order that the two shafts and all the partswhich are carried thereon may be moved at the same speed and caused to properly register, as will be understood hereinafter. Upon the shaft b, between the side frames, is secured the moldwheel b,of suitable form, and provided upon its periphery or outer face with a series of moldsfli, invwhich the brick to be repressed is placed and held while under operation. I have herein represented this wheel as prpvid'ed with four molds; but it is evident at once that it may be provided with one mold or a dozen, accord- Serial No. 251,211).

ing to its size and the cost and desired capacity of the machine, and that the particular number of these molds will make no difference in the principle or operation of my invention,

the molds being co nstructcd and operated alike,

through a slot in the mold-wheel and contactsat proper times with a-cam or incline, a", secured to the main side frame around the shaft 1), as will be clearly seen in Figs. 1. and 5. Upon one side of each mold-box is also a pro ecting p'in, b",the purpose of which will be presently seen.

Upon the shaft 0 is secured the plungerwhcel c", which is at its periphery provided with a plunger or plungers corresponding in number and location with the molds with which they operate. These plungers c are pivoted in suitable jon rnals on the plungenwheel, andarc each provided with a spring, e",wh1ch holds them normally at an angle with the periphery of the wheel, and upon'one end of the pivot or journal eaeh'is provided with an arm, cflwhieh projects in opposite directions from said pivot, one end resting normally against a step, c, and the other projecting beyond the plunger-wheel to engage the projecting pm I) on the mold-box.

In operation power is applied from any dosircd motor to either of the main shafts, and the machine being started it is evident that the molds and plungers will be moved together at a uniform speed.

This machine is intended for re-prcsslng bricks formed in another machine, and as the moldwheel revolves the formed brick is placed in the mold as it is at or near its highest point. The mold and brick are carried around till they assume the position of Fig. 1, where the outer 5 plunger is shown as just entering the mold, it being understood that the angle at which this plunger is held is such as to cause it to properly register with the mold as they meet. At the same instant the arm 0" engages the pro- IOO jecting pin 1) on the mold, and during the further motion,while the pivoted outer plunger is being'forced into the mold to press the brick down upon the inner plunger, this arm holds the plunger and mold in constant alignment,

1 so that there will be no tendency to bind, and

asthe two wheels continue to revolve and the plunger is drawn back the arm holds its position till the plunger and mold are entirely separated, as in Fig. 5, when the arm slips off the pin b and allows the spring to throw the plunger back to its normal position, ready for engagement with the mold again on its next revolution. At this time the lateral projections d on the inner plunger engage and ride up on the inclines or cams, and at the time the mold has reached the lowest point of its motion its face has been advanced through the mold to its outer edge, as in Fig. 2, and the brick being entirely pushed out of the mold drops off upon the belt a below, by which it is carried to the point of delivery. Abar, g, in the main frame serves to sweep the brick off the plunger ifit should stick and fail to drop at this point. The continued revolution of the mold carries it past the end of the cam or incline, and its spring draws the plunger back to the bottom of the mold,ready for another brick. This operation is repeated for each revolution and each mold-box, and the whole form a simple repressing-machine. The delivery-belt is drawn bya belt-connection, g, with one of the main shafts.

I have herein called the revolving devices which carry the molds and plungers wheels; but it is obvious that this is only adistinguish ing name and has no reference to any necessary form, as the latter may be in the shape of radial arms instead of a wheel; but this would I 40 not affect the'principle of my invention. For

the most perfect operation I prefer to so locate the pivoted plungers that their centers shall be aligned with the pitch-line of their drivingbination, with a revolving mold-box provided 55 with a projection on one side, of a pivoted plunger revolving about a different point of the machine, said plunger being provided with a spring to return and hold it normally at anangle to its line of rotation, and an arm to engage the mold-box and turn said plunger on its pivots in exact alignment with the mold during their engagement, substantially as and for the purpose set forth. y

2. In a brick-repressing machine,the combination, with the revolving mold-box b and its plunger d, formed with lateral projections d, and provided with a retracting spring, .1 and the inclines or cams a, of the pivoted revolving plunger 0 its spring 0, arm o and stops 0 b", the gears 12 c, and delivery-belt a, all constructed and arranged to operate substatially as and for .the purpose set forth.

In testimony whereof I affix'my' signature in presence of two witnesses.
